Good evening together, today he has a 2016 AGM GMX 450 of the kinship in maintenance. Currently about 5500KM ran. Maintenance kit, brake cheeks at the rear and front renewed, brake fluid renewed (established that the sight glass is leaking ;-( – glued so that it can hold somehow over the days. But is replaced as soon as possible. Engine and transmission oil renewed. Vario cleaned, rolls new, belts renewed air filter still Ok, left. Everything built together, started and driven about 100m (easy Be rg hoch) When turning around then went out (nothing noticeable noticed) and since then it doesn’t start any more. Starter E starts, but it no longer starts, kick starter without success. Mechanically everything seems ok here. Then everything looks again, no hose snapped off or something like that (Sprit is in it, mini air bubble In the filter moves when you organ (looked at by opposite light) ignition spark is there, plug on the housing and EStarter actuated. Ignition plug renewed on suspicion, since anyway there was – without success Would say slightly damp, but not wet or arduous dry. Short tank lid down, if vacuum – but was not OK and sprang on. Someone else an idea, what I could have screwed up here? Have done the same with my Sym Fiddle 3 from 2015, there was everything Ok After that… Dear thanks and a nice weekend Oliver
